WebDescription. k = find (X) returns the indices of the array X that point to nonzero elements. If none is found, find returns an empty matrix. [i,j] = find (X) returns the row and column indices of the nonzero entries in the matrix X. This is often used with sparse matrices. [i,j,v] = find (X) returns a column vector v of the nonzero entries in X ... WebLet T: P 3 → P 2 be defined by. T ( a + b x + c x 2 + d x 3) = a x 2 + b. B = { 1, x, x 2, x 3 } B ′ = { 1 − x + x 2, 1 − x, − 1 } Find the matrix [ T] B ′, B of the linear transformation T with respect to the bases B, B ′. Now, I know that T is an operator and that the question is asking for you to find the transformation matrix ...
